Comments on 'A decision feedback recurrent neural equalizer as an infinite impulse response filter'

摘要

This correspondence corrects and clarifies some notation inconsistencies and the absence of some definitions in a previous paper by Ong et al. (see ibid., vol. 45, p. 2851-8, Nov. 1997) In addition, we show that the assumptions made in the derivation of the MSE/sup DFRNE/-MSE/sup RNE/ invalidate the final result given in Ong et al. and lead to an unfair comparison between the two equalizers. We present a simulation that best compares the two equalizers.
